WATER-HEATING GAS-BURN ER.

SPECIFICATION forming part of Letters Patent No. 450,634, dated April 21, 1891. Application filed December 9, 1890. Serial No. 374,073. (No model.

To all whom it may concern.-

Be it known that I,\VILLIAM HENRY MUNN, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in \Vaterdleating Gas-Burners; and I do declare the following to be a full, clear, and exact description of the inventiomsuch as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon which form apart of this specification.

The object of my invention is to furnish a gas-burner with a hollow top to connect with a water-reservoir for keeping a supply of hot water while using it or not for other purposes.

It consists in constructing the burner in a novel manner of two parts, the upper part being hollow for receiving the water and forming a cap for the lower part,which recci ves the gas.

In the drawings, Figure l is a perspective view of my invention. Fig. 2 is a vertical section on the line 2 2 of Fig. 1; and Fig. 3 is a vertical section on the line 1 1 of Fig. 1, also showing the device attached to the interior of a case provided with a perforated cover and a cooking utensil thereon.

A and B form the two parts of the burner, A being the upper or top part for receiving the water, and B the lower or bottom part of the same for receiving the gas. The bottom B is made bowlshaped, open at top, with a tubular passage Z) through its center, terminating in a rim of the same height as its exterior edge; also, with a pipe 13 on one side for receiving the gas-supply into the space I), and also with an arm G for attaching it to a wall or inner side of a case K with bolt and nut g and 9 as shown in Fig. The top or up per part Ais made hollow with a cen tral tub ular passage through it corresponding to the tubular passage 1) through the bottom part B. Its exterior and interior sides are made to incline outwardly from its bottom edge. In-

let and outlet pipes F F extend from its sides to connect its interior a with a waterreservoir (not shown) in the usual manner. The top A and bottom B thus constructed are arranged with their inner tubular openings concentric and with parting-strips a interposed, so as to allow a narrow combustion-space a between the outer and inner edges of the bottom B and the lower edge of the top A for the passage of the gas when burning, as shown in Figs. 2 and 3. The parts may be rigidly attached by the partingstrips a, or may be connected by means of spiders II and E and a bolt 0, as shown in Fig. 2. The burner thus constructed is attached to a wall or to the inner side of a casing K by a bolt g and nut. g as shown in Fig. 3. The casing may have aperfora-ted top I, on which to place a pot J or other utensil, as shown in the same figure. When located, the inlet and outlet pipes F F of the upper part are connected with a water-reservoir (not shown) in the usual manner, allowing the water to pass into and out of the hollow space a of the upper part, and the lower part is connected with the gasmain (also not shown) for the admission of the gas into the space b of its body. When lighted the flame will surround the exterior sides of the upper part of the burner, heating the water passing through it. At the same time the flame may be used for stoves or any other desired purpose.

Having thus described my inventiomwhat I claim is i 1. A water-heating gas-burner consisting of an open annular bowl-shaped bottom for receiving the gas and a hollow annular top or cover forming a circulating water-chamber so located above the bowl-shaped bottom as to leave a space between them forming a burner-opening for the passage of the gas, as shown, and for the purpose set forth.

2. A water-heating gas-burner consisting of a bowl-shaped bottom having a central tubular passage and pipe for gas-connection and a hollow top havingacorresponding central tubular passage and inlet and outlet pipes for water-connection, arranged with their tubular passages concentric and with a narrow opening between their adjoining edges, as and for the purpose set forth.

I11 testimony whereof I aiiix my signature in presence of two witnesses.
